Array isArray (0 =>3,2 =>4,3 =>5,5 =>6)In the Json_encode array, the subscript discontinuous array is parsed into a JSON string such as {"0": "3", "2": "4", "3": "5", "5": 6}.

When creating a value type instance, we should try to implement it as constant and Atomic. The so-called constant, that is, the object will not be changed after it is created, similarProgramA constant defined in. Once a value type is created, it can be regarded as a constant state. In this way, it is thread-safe. Atomicity refers to some correlated fields in the value type, such as birthdate and age. Age is calculated based on birthdate. if the objec

Go back in the evening to review the original information, return to the codebook there is a "expand a nested Sequence" topic.Task description: The child in the sequence may be a sequence, the child of the subsequence may still be a sequence, and so on, the sequence nesting can reach any depth. You need to loop through a sequence and expand all of its subsequence into a single sequence with only the basic subkeys.For example, the shape is the following sequence a: a = [(123 (78)]" , 45, 69, 10

Otherwise, China may be able to successfully develop an atomic bomb in early 300, but it is clear that the power of the atomic bomb is beyond the control of humans at that time.Hey, I'm afraid it's not a blessing. At that time, all humans may be threatened. The big bang of the Wang Gong factory will make the Ming Dynasty's nuclear technology a torch, and the horse will fall out of service, maybe this expl

Atomic means that the setter/getter function is a primitive operation. If multiple threads call setter at the same time, there will be no execution of setter by another thread before executing all the setter statements, which is equivalent to adding a lock at the beginning and end of the function. Nonatomic does not guarantee the primitive line of setter/getter, so you may get incomplete things.For example, if you use nonatomic to change two member va

When the Linux kernel prints "bug:scheduling while Atomic" and "bad:scheduling from the Idle thread" error,It is usually called in the interrupt handler function that can sleep, such as semaphore,mutex,sleep, such as a dormant function,While the Linux kernel requires interrupt processing, the system is not allowed to dispatch, not allow preemption, wait until the completion of the interrupt processing to do other things.Therefore, to fully consider th

It was only today that C++11 supported atomic operations and also supported the thread class to create threads, which is really getting 6. Before doing the project, the creation thread is the POSIX standard pthread_create function, and the thread synchronization is generally used Pthread_mutex. Today get a new skill, you can use the thread class to create a thread, with the Atomic_flag implementation of spin lock for thread synchronization, do not say

synchronization, two threads may enter the IF statement block at the same time, causing each thread to get a different existingvalue, which is clearly not desirable. Looking back at code 1-1, we understand the author's deep meaning. The thread-safe Putifabsent method provided by Concurrenthashmap guarantees the thread safety of the storage deposit, while the Newkey, Existingkey (in fact, should be named NewValue, Existingvaule) Two-thread variable value judgments are returned to ensure the

It is not a specific technical issue. I just come here to ask you a solution. For example, if there is a record in the database, the field is as follows: idfile1avatar.png, a record corresponds to a file. If the delete operation needs to delete the file corresponding to the record in the database at the same time, if the number is guaranteed... it is not a specific technical issue. I just come here to ask you a solution. For example, if there is a record in the database, the field is as follows

Zookeeper based on Zab (Zookeeper Atomic Broadcast), the system architecture in the master and Standby mode is implemented to maintain data consistency among the replicas in the cluster. The ZAB protocol defines the four stages of an election (election), Discovery (Discovery), Sync (Sync), broadcast (broadcast). Election (election) is the selection of the host, the Discovery (Discovery), synchronization (sync) when the main elected, to do the recovery
